       4. The HMD of  claim 1 , wherein
 the first pixel density is a higher pixel density than the second pixel density, and 
 the third display portion is configured to reduce a brightness of a portion of the image projected by the third display portion, the portion of the image projected with reduced brightness by the third display portion corresponding to the image projected by the first display portion and the second display portion. 
 
     
     
       5. The HMD of  claim 1 , wherein
 the first pixel density is a lower pixel density than the second pixel density, and 
 the first display portion and the second display portion are configured to reduce a brightness of a portion of the image projected by the first display portion and the second display portion, the portion of the image projected with reduced brightness by the first display portion and the second display portion corresponding to the image projected by the third display portion. 
 
     
     
       6. The HMD of  claim 1 , wherein the two images are blended at a boundary between the two images. 
     
     
       7. The HMD of  claim 1 , wherein the HMD is communicatively coupled to a computing device configured to generate the two images using an optical fiber. 
     
     
       8. The HMD of  claim 1 , wherein
 the first pixel density is a higher pixel density than the second pixel density, and 
 the first display portion and the second display portion are positioned above the third display portion. 
 
     
     
       9. The HMD of  claim 1 , wherein at least one of the first display portion, the second display portion and the third display portion include a curved portion. 
     
     
       10. The HMD of  claim 1 , further comprising at least one lens. 
     
     
       11. The HMD of  claim 1 , further comprising at least one of a motion sensor and an eye tracking component each configured to detect a change in a view position of a user of the HMD. 
     
     
       12. A head mounted display (HMD) of a virtual reality (VR) system, the HMD comprising:
 a first combined display system configured to receive a first image, the first combined display system including:
 a first display portion configured to project a first portion of the first image, 
 a second display portion configured to project a second portion of the first image, and 
 an image combiner configured to optically combine two images by reflecting light rays representing the first portion of the first image and allowing light rays representing the second portion of the first image to pass through the image combiner, the image combiner including a region configured as a transition between the first portion of the first image and the second portion of the first image; and 
 
 a second combined display system configured to receive a second image, the second image being a different view perspective of the first image, the second combined display system including:
 a third display portion configured to project a first portion of the second image, 
 a fourth display portion configured to project a second portion of the second image, and 
 an image combiner configured to optically combine two images by reflecting light rays representing the first portion of the second image and allowing light rays representing the second portion of the second image to pass through the image combiner, the image combiner including a region configured as a transition between the first portion of the second image and the second portion of the second image. 
 
 
     
     
       13. The HMD of  claim 12 , wherein the HMD is communicatively coupled to a computing device associated with an image repository via an optical fiber. 
     
     
       14. The HMD of  claim 12 , wherein
 the first display portion and the second display portion have a first pixel density,
